Special Containment Procedures: SCP-3XXX is currently being contained in Provisional Sector 3 of Area 17. SCP-3XXX is to be contained in a 4 x 4 x 4 m. ice-proof glass chamber with a 10 mm thick iron roof. A steel railing 2 mm thick must be placed around SCP-3XXX along with an elevator moving from the top of SCP-3XXX's containment chamber to the bottom of SCP-3XXX. All subjects who go past the railing must stand clear 1 m. from SCP-3XXX to reduce subject injuries and/or death.

SCP-3XXX's containment chamber must have two floors: the main floor with SCP-3XXX and everything included in the first section of the procedure and a second floor serving as a "watch area" and containing the controls for the elevator. The second floor can only be accessed by Site Security and Foundation researchers due to recent maintenance issues of SCP-3XXX's containment chamber.

Any investigation of SCP-3XXX must be done by Epsilon-11 personnel and allowed by the Site Director. Any other investigation by any other squad and/or personnel will not be allowed.

Description: SCP-3XXX is a large ice crater with a 7° m. diameter with thick gourmet ice layers located in ████ ████, Antarctica, which origins remain unknown. SCP-3XXX possesses many layers that make SCP-3XXX tougher. SCP-3XXX's first layer has a smooth, but hard crust made of ice which is resistant to physical damage. The second layer is composed of harder gourmet ice, but more of this layer has more hydrogen atoms than the usual H2O composition and blocks off oxygen from SCP-3XXX. The last layer is composed of unknown materials since no person has been able to dig completely through SCP-3XXX's layers.

The effect(s) caused by SCP-3XXX to other subjects and SCPs are as follows:

1. Since SCP-3XXX blocks of oxygen, the subject(s) and other human SCPs are already weakened if they don't wear oxygen masks if they aren't already provided. SCP-3XXX releases a dry ice neurotoxin if any oxygen manages to get past the second layer of SCP-3XXX.

2. If the subject/SCP is still alive or manages to resist the effect, SCP-3XXX freezes on point where the subject/SCP is standing on, freezing the subject/SCP from the waist to the feet. SCP-3XXX then entraps the subject/SCP in a cold, hard block of ice.

3. If the subject/SCP manages to break this block of ice (which is certainly impossible), SCP-3XXX will then start to block any subject/SCP from the surface and crushes them into walls of dry ice. The dry ice wall will hold for about 3-5 minutes.

SCP-3XXX was first found by a mining expedition crew who went ice harvesting for future research. An hour after the team had found their harvesting area, one of the expedition members went scouting to take scenic pictures of the landscape, but unfortunately fell deep into SCP-3XXX. Upon the death of the expedition member, MTF Zeta-9 was sent in to investigate the following death and SCP-3XXX. All expedition personnel was ordered to leave the following area.

There have been multiple locations that SCP-3XXX has been seen by the public eye. One location has been seen at █████ █████, Ohio, United States, located northwest of the campgrounds and has been registered as SCP-3XXX-01. Another location has been seen at ██████, Iowa, United States, eastwards of the city and has been registered as SCP-3XXX-02. The last location of SCP-3XXX has been seen at ██████, Sweden and has been registered as SCP-3XXX-02. These instances of SCP-3XXX do not connect to each other but have the similar effects caused by SCP-3XXX.

Addendum 3XXX-01: Due to recent experiments involving subject deaths and multiple injuries to Foundation personnel, testing purposes of SCP-3XXX are to remain on hold as of ██/██/████.

Addendum 3XXX-02: Testing purposes are to be continued as of ██/██/████ by orders of Site Director █████. Containment purposes with SCP-3XXX will still be continued.

Addendum 3XXX-03: The origin of SCP-3XXX has been found by Foundation personnel using several ancient paintings dating to the Stone Age. SCP-3XXX was caused originally by small rises in temperature during the day that reached to about 15°F (-9°C). These rises in temperature caused melting to the nearby ice caps, which allowed for openings to the surrounding waters. The melting ice caps collided with the landscape SCP-3XXX laid on and caused more openings to occur in SCP-3XXX. The opening was blocked off by more of the colliding ice caps and froze with SCP-3XXX.

The temperature again rose and there was soon a small cave that grew inside SCP-3XXX. The cave was soon discovered by English explorers who settled on the nearby ice caps while counterstriking American forces on the southern border of the Atlantic ocean. The explorers were very interested in the foundation of SCP-3XXX and decided to launch a mining project that would last for 9 (nine) years. Unfortunately for these explorers, the mining project closed when an avalanche occurred and blocked off SCP-3XXX.

09:42 - SCP-966 runs to cafeteria. Five personnel were injured and two personnel were killed by SCP-966. Security agents try to contain SCP-966 but fail to do so. Security Captain Domino, along with six other agents and Class-D Subject D-3429, guide SCP-966 to SCP-3XXX.

09:55 - Security Agent Kicker activates the elevator. The elevator comes up and SCP-966 lies on the elevator's floor, unconscious.

10:01 - Security personnel cages SCP-966 and brings it back to its containment chamber. Breach alarm is deactivated and a cleaning team is sent to SCP-3XXX's chamber. Injured personnel are sent to the medical bay.

Note 1:"You have actually got to be kidding me. SCP-966 can't be taken out that easily, can it? I mean, looking from SCP-966's file it's one of the most dangerous anomalies of the Foundation." - Technician Supervisor Dwight

Note 2"I'm actually about to laugh about what this incident report has to say." - Senior Researcher Barkley

Incident Report 3XXX-106

SCP(s): SCP-3XXX, SCP-106Date: ██/██/████

11:15 - SCP-106 test begins. Researcher Stryker tells security agents to guard the perimeter of SCP-106's chamber. One agent stands in front of the door and the other guards the area surrounding SCP-106's chamber.

11:18 - Electromagnetic supports in SCP-106's chamber shut off (due to faulty wiring), allowing SCP-106 to breach the chamber and escape. Researcher Stryker alerts the agent guarding the interior to turn on the breach alarm. Researcher Stryker then tries to escape the room, but SCP-106 appears behind him, sending Stryker to the "pocket dimension".

11:22 - Site Security are immediately alerted and all Foundation personnel are sent to the breach shelter. Epsilon-11 personnel are alerted to revert the crisis and 'escort' SCP-106 to SCP-3XXX by orders of Epsilon Task Leader ██████.

11:26 - Epsilon-11 personnel escort SCP-106 to SCP-3XXX. SCP-3XXX's containment chamber door is opened and personnel guide SCP-106 down. Any corrosions done by SCP-106 on SCP-3XXX are blocked by SCP-3XXX's resistant layers. SCP-106 walks around SCP-3XXX and sends two of the personnel to the "pocket dimension".

11:30 - Site Security help Epsilon-11 to get SCP-106 in SCP-3XXX. Whilst distracting SCP-106, Epsilon-11 Agent Henrik runs upstairs to the watch area and sends the elevator to the first floor while SCP-106 takes one more Site Security agent.

11:32 - SCP-106 walks into the elevator and Agent Henrik sends the elevator down. SCP-106 is lowered to the bottom floor and remains confused. SCP-106 sends out a corrosion affect that only pushes through half of the first layer. SCP-3XXX closes on SCP-106 and entraps SCP-106 in a block of ice weighing 44 kg. The elevator is brought back up with SCP-106.

11:35 - Maintenance is sent to SCP-106's containment chamber to fix the broken electromagnetic supports caused by faulty wiring and SCP-106 is sent back to its chamber and defrosted to continue testing.

Outcome/Result: Two (2) Epsilon-11 agents and one (1) Site Security agent dead. SCP-106 remained frosted for three (3) minutes and could not break the ice made by SCP-3XXX.

Note:"Maintenance should always check these technologies to see if they're up-to-date. If this isn't up-to-date, more breaches will happen and cause more deaths." - Site Director ███
